Tractors are self-propelled power machines used to pull and drive operating machinery to complete various mobile operations.

It can easily accomplish many things that would otherwise be time-consuming and labor-intensive.

Such a huge thing consists of many parts, and a failure will make people a headache, next, you can learn about the repair methods for common failures.

1. High-pressure oil pipe wear and leakage.

Tractor high-pressure oil pipe at both ends of the convex head and injectors, oil valve connection wear leakage, can be cut from the waste cylinder gasket on a round copper skin, the middle of a small hole, pad in the convex pit between.

2. Suddenly insufficient oil supply.

Insufficient oil supply in tractor operation, if the air is discharged to replace the plunger after the nozzle still does not work, that is, the injector of the oil injection needle top bar small steel ball bias grinding so that the oil injection can not be atomized.

At this point should be replaced by a small steel ball, such as a no-steel ball can also be used instead of a bicycle flywheel.

3. steering wheel shaking, front wheel swing head.

The phenomenon of steering wheel shaking and front wheel shaking is mainly due to improper positioning of the front wheel, and the rear camber of the main pin being too small.

In the absence of instrumentation, you should try to add a wedge-shaped iron piece at the rear end of the steel plate spring and front axle support plane, so that the front axle back turns, and then increase the rear tilt angle of the main pin, after a trial run can be restored to normal.

4. Free jumping gear after shifting.

Tractor operation, after shifting the phenomenon of free jumping gear, mainly due to the wear of the fork shaft slot, fork spring weakness, and linkage joint part clearance is too large.

At this time, the positioning groove should be repaired, the fork spring should be replaced, and the clearance of the connecting rod joint should be reduced.

5. Poor performance of oil pump.

To solve the problem of the oil pump not coming up after overhaul or overhaul, the oil filter or oil pipe should be removed, and then the oil injector should be filled with oil from the oil hole of the body, and the filter or oil pipe leading to the oil indicator should be put on immediately.
